Trouble accessing JF using server name

[kiwichick]

Server installed on Windows 10 Pro 22H2
Server version 10.10.3

My ISP is Starlink so my IP Address changes regularly so I connect using the server name instead of the server IP Address. I used to be able to access JF on all my other devices this way - PC browser (Windows 10 Pro 22H2, not the same PC as the server), Android TV app, Android mobile app, Android mobile browser - but now only my PC browser works. On all other devices I get a 'unable to reach server' error. It tries both http and https with no success. Can anyone shed some light on what might be happening?

Are all these devices on the same home network?

Oh geez, didn't think about mentioning that. Yes they are all on the same local network.

Can you share your jellyfin logs via pastebin? And do you have a VPN running on the server?

No, I'm not running a VPN on the server. I had a look at the docs about JF logs but I found them confusing and I don't understand what I need to do.

Just copy and paste the logs into pastebin.com

Thanks, I obviously wasn't very clear about my confusion. I know what to do withh the logs but I don't understand how to get the logs.

Thank you. I have several log files. Do I just post the most recent one?

Yes.
